Forging Process Yes No N/A 18 Operation description: 1) Explain the actual hammer or press steps (approximate number of blows or strokes) in the forging (reduction) process being reviewed? 2) Is the percent reduction controlled for each step? 3) Is a minimum reduction required by the customer? 4) Is the minimum reduction that is required measured and ensured? How? 5) Is it necessary to control the primary working direction (grain flow) of the final product? If yes, how? 6) Is there heat conditioning (re-heating) between forging cycles? If Yes, How is temperature controlled? 19 Maintain identification traceability: 1) Is the original mill traceability identification maintained during the forging operation on the traveler or on the work piece? 2) Is the forging unique identification physically applied to provide traceability to the modified mechanical properties? 3) How is the physical identification marking applied and who verifies proper marking? 20 Surface Preparation: 1) Is the forged surface cleaned (de-scaled) and prepared for heat treatment or further processing? 2) Is there a procedure? a) Procedure # 3) Is shot blast used? a) If so, what type of medium is used? If steel shot is used, how is iron contamination of nonferrous forgings prevented? 4) Is it recycled, and is the same shot blast used on all alloys? 5) If shot blast is not used, how are forgings cleaned after removal from the die or hammer? 6) Is pickling or other cleaning method used?

Forging Process Yes No N/A 7) Is the physical forging identification marking verified after surface treatment, if applicable? a) Who verifies proper marking? 21 Process Control: 1) Is there an observer or QC over check at the forging operation? a) Describe function and authority: b) Are internal audits performed to verify procedure compliance? Verify by reviewing sample records. i) Sample records reviewed: c) How are deviations handled? 22 Method to obtain mechanical test specimen: 1) Is a forging drawing required for location of test specimen? 2) If so, is approval by the customer necessary and obtained? 3) Verify the test samples conform to the forging drawing? 4) Is a production forging or prolongation used to obtain test specimen? 5) Is the sample location & orientation correct per the specification, forging drawing, or customer requirement? 6) Is a separate specimen forged specifically for mechanical testing? a) Same heat of material? b) Same process steps as forging, as closely as possible? c) Same size (cross section) as forging? d) Representative of forging? 7) Is the number of samples controlled (tensile tests, elevated tensile, charpy, hardness, grain size, micro cleanliness, corrosion, etc.) as required by specification?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
